Answer: 1)
2)
3) 13, 4) 10.
Step-by-step explanation:
Since we have given that

So, we need to find :
1) a + b is given by

2) 2a+3b is given by

3) |a| is given by

4) |a-b| is given by

Hence, 1)

3) 13, 4) 10.
Answer:

Step-by-step explanation:
T is a linear transformation, hence it is homogeneous (T(cr)=cT(r) for all real c and r∈ℝ³) and additive (T(r+s)=T(r)+T(s), for all r,s∈ℝ³). Apply these properties with r=3u and s=2v to obtain:

We don't have an explicit definition of T, so it's more difficult to compute T(3u+2v) directly without using these properties.
Answer:
y = 2
Step-by-step explanation:
not sure but should be it
Answer:
B.
Step-by-step explanation:
because they have the same base and it's a multiplication so you have to add the exponents
